SPRING-BED.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed October l5. 1903. Serial Nol 177,167.

To (LZ/f whom zt nifty concern:

Be it lrnown that I, GEORGE E. BiGELow, a citizen of the United States,residing at lilorcester, in the county of lVor-cester and State ofMassachusetts, have invented a new and useful Spring-Bed, of which thefollowing is a specification.

This invention relates to that class of spring bed-bottoms which arepreferably constructed entirelyT of metal.

The especial objects of this invention are to provide a strong, simple,efficient, and inexpensive bed-bottom of what is known as the rabbetedor projecting-edge type in which two different sizes of springs arecombined so as to prevent the swaying or sidewise motion of a mattresssupported thereon, to provide for fastening the lower ends of thesprings and the stay-wires to sheet-metal cross-strips in a simple anddirect manner, and to fasten the tops of the springs together by meansof binding-adres fastened in place by a novel form of sheet-metal clip.

To these ends this invention consists of the spring bed-bottom and ofthe parts and oombinations of parts therein7 as hereinafter described,and more particularly pointed out in the claims at the end of thisspecification.

In the accompanying two sheets of drawings, Figure 1 is a perspectiveview of suflicient-parts of a spring bed-bottom to illustrate theapplication of my invention thereto. Fig. 2 is a plan view of the blankfrom which one of my binding-wire clips is made. Fig. 3 is a perspectiveview of a binding-wire clip constructed according to this invention.Fig. et is a bottom view thereof, showing the relation of the tongueswhen the clip is fastened. Fig. 5 is a side view, partially broken away,of the bed-spring bottom. Fig. 6 is an enlarged perspective view showingthe manner of assembling one of the springs and the crossstrip therefor;and Fig. 7 is a fragmentary view, partly in section, showing theoperation of the tool for fastening a cross-stripV spring and stay-wiretogether.

A spring bed-bottom constructed according to this invent-ion comprises asupport or bottom frame, the springs which are mounted upon the support,and the wires which fasten the tops of the springs together. The supportfor the springs comprises a number of sheet-metal cross-strips which areset up edgewise, so as to stand in vertical planes. Each of thesecross-strips has a quarter-turn and a bent-up portion at each end, whichis bent outwardly to form the foot or support by means of which thespring bed-bottom may be hung in a bedstead-frame. Riveted to thebent-up portions of the cross-strips are the edge strips, which alsostand in vertical planes above the cross-strips. The edge strips areconnected at their ends by end strips, and mounted in the edge stripsand these end strips are short coiled springs,while mounted on thecross-strips are the fulllength coiled springs or body-springs, whichare larger than the springs around the edge of the construction. Thiscombination of the ordinary springs with smaller marginalsprings isregarded as a desirable feature of construction, because when the topsof the springs are bound together by the ordinary tie-wires thedifference in the lengths of the springs will prevent the swaying orsidewise motion of a mattress supported on top of the bed-spring bottom.

The tie-wires which connect the tops of the springs are preferablyfastened in place by a novel form of sheet-metalv clip, and thestaywires which form part of the support are preferably connected to thecross-strips at the same operation which is required for fastening thefurniture-springs in place-that is to say7 the cross-strips are providedwith perforations or recesses, each of which is adapted to receive oneof the stay-wires as well as the supporting-coil of a spring, so that bybending down the metal above the perforation so as to close the same arigid fastening will be secured bot-h for thel spring and thestay-wires.

Referring to the accompanying drawings for a detail description of aspring bed-bottom constructed according to this invention, as shown inFig. 1, the support comprises the sheet-metal strips 10, which are setup edgewise to stand in vertical planes. Each of the sheet-metal strips10 is bent with a quarterturn 11 and is provided with anupwardlyextending section 12, having the outwardlybent foot 13. Thesefeet 13 are employed for hanging the spring bed-bottom in abedstead-frame. Riveted to the upwardly-bent portions 12 of thecross-strips 10 are sheetmetal edge strips 14, which are also set up onIOO . (L and b.

edge to stand in vertical planes. Connecting the ends of the edge strips14 are the end strips 15. Mounted on the edge strips 14 and end strips15 are short or small coiled springs 16, and mountedin the body portionof the cross-strips 10 are the full-length bedsprings 17.

The cross-strips 10 and end strips 15 are connected by staywires 18.rlhe same joints which fasten the springs in place in the cross-stripsalso serve to fasten these stay- Wires. rlhe construction which l employfor this purpose is most clearly illustrated in Figs. 6 and 7. As shownin these figures, each of the strips 10 is provided near its upper edgewith specially-shaped recesses or slots for receiving both theattaching-coils of the spring and the tie-wires. As shown in Fig. 6,each of these slots is preferably provided at its ends with pinchingsections or recesses 19 and at its center with a tie-wirereceivingrecess 20. p In assembling theparts, as shown in Fig. 7, the lower coilor other attaching-coil of a spring is inserted into the recess. Thetie-wire 18 is threaded into place below the same, and the parts arerigidly fastened together by driving down the metal forming the upperside of the recess, this preferably being done by means of an upsettingor peoning tool, as shown in Fig. 7. ln a prior patent, granted to meJanuary 30, 1906, No. 810,902, l have shown a similar joint for securinga spring in its supportingstrip, with the exception that the joint shownin said case is not also designed to secure a stay-wire in place. Inthis application for patent I do not wish, therefore, to claim this formof joint broadly, the claims of this application for patent so far asthis feature is concerned being intended to be limited to the use of asingle joint of this form for fastening both a spring and a stay-wire.

The upper ends of the springs 16 and 17 are connected together bymarginal wires 21 and binding-wires 22.

Figs. 2 to 4, inclusive, illustrate a form of clip which l preferablyemploy for fastening the binding-wires in place. As shown in Fig. 2, theblank from which each of these clips is formed consists of a bodyportion having upon one side converging or relatively inwardly--inclinedclamping-tongues 23, which are bent at right angles with respect to thebody portion upon dotted lines At its opposite side the body portion ofthe blank is provided with diverging or outwardly-inclined tongues 24,which are folded at right angles to the body portion of the blank uponthe oblique or inclined dotted lines c d. The central part of the blankis provided with a curve or arch 25 for receiving the binding-wire. Byproviding the clip on one side with converging tongues which are bent upon the straight lines a b,

While the other side of thel clip is provided with diverging tonguesbent up on the oblique lines c d, I have provided a form of cli in whichthe fastening-tongues may be le 't long enough to lap past each other,as shown in Fig. 4-that is to say, when the ends of thefastening-tongues are bent over or clamped into position they willintermesh, the converging tongues 23 lying between the diverging tongues24, which fold outwardly.

The clips which are employed for fastening the springs to the marginalwires 21 may be of substantially the same construction as illustrated inFig.- 3, except that the central arch or curve 25 between theclampingtongues may be omitted.

I am aware that numerous changes may be made in the construction ofspring bedbottoms by those who are skilled in the art without departingfrom the scope of my invention as expressed in the claims and thatspecial features of this invention may be applied and used in theconstruction of bedbottoms or similar articles of widely-different typefrom that herein shown. l do not wish, therefore, to be limited to theconstruction l have herein shown and described, but p l/Vhat l do claim,and desire to secure by Letters Patent of the United States, is-

1. In a construction of the class described, the combination of asheet-metal supporting-strip having a slot or recess near its upperedge, a spring having a coil thereof inserted in the socket, and astay-wire also threaded through said socket, said parts fastenedtogether by bending down the material above the slot or recess.

2. In a construction of the class described, the combination of asheet-metal strip having a slot or recess near its upper edge withtapering pinching-sections at its end, and a stay- Wire socket betweenthem, a spring having one coil inserted through the slot or recess witha staywire threaded through the recess below the coil, said partsfastened together by bending down the material above the slot or recessto fasten the coil in the pinching-sections at the ends of the slot andthe wire in the socket between said pinching-sections.

3. In a bed-spring, the combination of a framework comprising sheetmetal Acrossstrips set up edgewise in vertical planes, each cross-striphaving a quarter-turn and bentup section at each end, side stripsconnected to the bent-up sections of the cross-strips,

Vshort coiled springs, each having a coil inserted through a socket in aside strip and fastened by bending down the material above the slot orrecess, longer coiled springs, and stay-wires fastened to thecross-strips by the insertion of the stay-wires and the coils of saidlonger coiled springs through sockets in the cross-strips, and held inplace by bending down the material above the slot or recess.

4. ln a bed-spring, the combination of a IIO IZO

framework comprising sheet metal crossstrips set up edgewise in verticalplanes each cross-strip having a quarter-turn and bentup section at eachend, side strips connected to the bent-up sections of the cross-stripsand standing in vertical planes7 short coiled springs each having a coilinserted through a socket in the sidestrips and fastened down by bendingthe material above the slot or recess down onto the same, longer coiledsprings and stay-Wires fastened to the crossstrips by the insertion ofthe stay-wires and the coils of said longer coiled springs in sockets inthe cross-strips and held in place by bending down the material abovethe I5 slot or recess, and marginal Wires and binding-Wires connectingthe upper ends of the springs together.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 2o Witnesses.
